1.2 Display Unit
1.2.1 Mounting considerations
The display unit can be installed on a tabletop, on the overhead, on the bulkhead or flush
mounted in a console or panel.
When selecting a mounting location for the display unit keep the following in mind.
•Keep the display unit out of direct sunlight.
•The temperature and humidity of the mounting location should be moderate and stable.
•Locate the unit away from exhaust pipes and vents.
•Keep the unit away from electromagnetic field-generating equipment such as motors and
generators.
•For maintenance and checking purposes, leave sufficient space at the sides and rear of the
unit and leave slack in cables.
•A magnetic compass will be affected if the display unit is too close to it. Observe the
compass safe distances to prevent disturbance to the magnetic compass.
Tabletop Overhead
Display unit, tabletop and overhead mounting method
1.2.3 Mounting procedure (tabletop, overhead)
1. Fix the hanger with four tapping screws (M5x20).
2. Screw knob bolts in display unit, set it to hanger, and tighten knob bolts.
1.2.4 Flush mounting
There are two types of flush mount kits, F type and S type. For details, see the outline diagrams
at the back of this manual.

3
F type
1. Make a cutout of 167 X 92 mm.
2. Attach the cosmetic panel (supplied) to the display unit with hex bolts (M6X12, supplied)
and spring washers (M6, supplied).
3. Fix the display unit to the mounting location with four tapping screws (5X20, supplied).
S type
1. Make a cutout 167 X 92 mm.
2. Attach two fixing metals (supplied) to the display unit with hex bolts (M6X12, supplied) and
spring washers (M6, supplied).
3. Screw four wing bolts (supplied) to wing nuts (supplied).
4. Fasten the display unit to the mounting location with four wing bolts and nuts assembled at
step 3.
1.3 Transceiver Unit
1.3.1 Mounting considerations
•Since the transceiver unit generates heat, install it in a dry, well-ventilated place. The cooling
fans at the top of the unit must not be obstructed, to allow heat to escape.
•This unit is designed for bulkhead mounting to permit dissipation of heat. If bulkhead
mounting is absolutely impossible, mount the unit on the floor leaving at least 50 mm
clearance between it and the floor to permit dissipation of heat.
•The unit weights 7.1 kg. Reinforce the mounting area, if necessary.
•Leave space around the unit for maintenance and checking. Refer to the drawing at the end
of this manual for minimum recommended maintenance space.
•A magnetic compass will be affected if the transceiver unit is placed too close to it. Observe
the compass safe distances to prevent disturbance to the magnetic compass.
1.3.2 Mounting procedure
Fasten the transceiver unit with four tapping screws (6X30, supplied).
For bulkhead mounting, make sure there is 5 mm clearance between lower edge screw head
and bulkhead.

1.4 Transducer Unit
The performance of this equipment is directly dependent on the installation of the transducer.
The installation of the transducer and the tank should be accomplished by a dockyard referring
to the installation drawings at the later part of this manual.
1.4.1 Mounting Location
To decide the location of the transducer, the following points should be taken into account.
•Locate the transducer of DS-80 at least 2.5 m from the transducer of an echo sounder.
STERN BOW
2500 mm or more
Recommended location
for echo sounder transducer ECHO SOUNDER TRANSDUCER
(a or b)
DOPPLER SPEED LOG TRANSDUCER

c
b
Transducer, mounting location
•Separate as far as possible from air bubble sources; e.g., side thruster and water disposal
pipes.
•Install in close proximity to the keel, for uniform water flow.
•Generally, best performance is obtained by mounting on the bow; the stern side is
influenced more easily by air bubbles and propeller caviation.
•Never apply ordinary paint to the transducer face. Whenever the ship is dry docked, the
transducer face should be cleaned off oysters and foreign materrial.

1.4.2 Mounting of transducer
Confirm that a metal cover is attached to the transducer. For seachest except DS-850, remove
the hose clamp from the top of transducer.
Mounting of Flush Type Seachest DS-850
1. Fit the transducer (1) and spacer (7) to the bottom plate (3).
2. With the “FORE” mark on the fixing plate (8) facing upward, pass the transducer cable
through the slot in the fixing plate (8).
3. Face the fixing plate (8) and bottom plate (3) in the ship’s bow direction, and then screw
three bolts (4) in the tapped holes of the bottom plate.
4. Fasten the fixing plate (8) with three flat washers (9), spring washers (10) and nuts (11) until
the fixing plate (8) contacts the spacer (7).
5. Set the tightening nut (12), washer (13) and gasket (14) to the transducer cable in that
order from the cable end.
6. Pass the transducer cable end through the though-hull pipe from below the hull.
7. Fasten the tightening nut (12) with the tightening handle (supplied) so that the length of the
cable between the tightening nut and the top of the transducer is 300 mm.
8. Mate the bottom plate (3) and barrel (2), and fasten them with six spring washers (6) and
hex. Bolts (5).
Note: The tank barrel needs not be filled with oil or any filler. Sea water will get into when the
ship is placed in the water.
Do not seal the bottom plate to stop ingress of water into the tank.
